The area with branching green lines on the left side of this image is the Okavango Delta, in Botswana. It is situated at the end of the Okavango River, where the river empties its waters onto the desert floor of the Kalahari. Also visible near the right edge is Lake Kariba.

Upon opening the full image, a stream can be seen connecting the inland delta to the Makgadikgadi Pan, a large salt flat. Although the salt flat appears bright white in the thumbnail, in the full image various colors can be observed: different shades of white and green, greenish areas where water is present, and red patches that probably indicate where salt is being extracted.
